Yeah it just feels more bland every year.
2010 - we got 6 skins for very different champions and the horrowin map, nothing that big since all those skins cost 975 RP, but still very good.
2011 - we got 2 skins for 520 skins and 2 950 and the map again, this was way better for players with low RP who wanted to buy a good Halloween skin, and all skins had great quality for what they worth, best event in my opinion.
2012 - we got 2 skins for 975 and 1 for 1820 and the map was changed for the opening of the new TT, in my opinion those 2 skins aren't that good for 975 rp, and the Brand skin while good quality, was kinda expensive, definitely a step back from last year, i'm not gonna mention the Shadow Isles skins since they don't count.
2013 - We got ALL previous skins from last year, only 1 975 skin and only 1 1350 skin... for a champion whose only other skin is 1350 as well, no new event, no new map either.
